TOOL-HOLDER.

SPECIFICATION forming part of Letters Patent No. 650,718, dated May 29, 1900.

Application filed August 30, 1899. Serial No. 728,985. (No model.)

To all whom it may concern:

Be itknown that I, WILLIAM HENRY CRAINE HARRISON, flour-mill proprietor, a subject of the Queen of Great Britain and Ireland, and a resident of Torrens road, Woodville, in the Province of South Australia, have invented certain new and useful improvements in means for carrying and attaching a plurality of tools or bits used in conjunction with a brace or other form of socketed handpiece, of which the following is a specification.

This invention relates to improvements upon the subject-matter of my-prior patent, No. 637,735, dated November 21, 1899, which relates to means for attaching and carrying a plurality of tools, commonly called bits, upon a brace or handpiece provided with a socket to take the tools, so that the tools cannot be mislaid and when required any one of them may be quickly secured in the socket of the brace or handpiece ready for use. In carrying out that invention I mount upon or attach to the brace or common handpiece a rotatable tool-holder or sleeve, to which the tools are hinged or attached at their tang end, so that when required to be used each tool may be turned on its hinge and quickly afixed in the socket and when done with may be swung from the socket and turned back on its hinge to lie along the sleeve without being detached from the sleeve. The improvements which I have made since the date of that patent relate to the means for hinging the tools to the sleeve and to the cap for protecting the points of the tools.

In order that my invention may be clearly understood I will describe the same with reference to the accompanying drawings, in which- Figure 1 is a side View of my invention applied to a carpenters hand-brace. Fig. 2 is a view of the tang end of the sleeve and the split socket. Fig. 3 Yis a central sectional View of a portion of the lower part of Fig. 1. Fig. 4 is a View of the tang end of the sleeve and tools with the outer disk removed. Fig. 5 is a section on line ay b of Fig. 3. Fig. 6 is avertical section of the two disks forming the ange at the tang end. Fig. 7 is a side View of myinvention applied to a simple handpiece. Fig. 8 is a central section of the same with the upper partof the handle broken 0E. Fig. 9 is a section from beneath on the line c d of Fig. 7. Fig. 10 represents the lower end of the stem, showing the tool-socket.

The general construction and operation areA described in my earlier patent, previously referred to, and will be easily understood from the drawings.

The following description of my improvements applies equally either to the construction shown in Figs. 1 to 5 or Figs. 6 to 9.

The sleeve 1 has at the end adjacent to the tool-socket 18 a flange composed of two specially-shaped disks 3 and 4, secured together and havinga number of radial slots 5 across the outer portion corresponding to the number of tools S to be attached. These slots divide the flange into a number of cheeks, between which the tools are secured. The inner disk 3 of the ange is rigidly attached to and forms part of the sleeve l, but the outer disk 4 is secured to the inner disk by means of set-screws, so that when desired the setscrews may be undone and the disks taken apart. Near the outer edge of each disk is an annular groove G of semicircular section, so placed that when the two disks are secured together the two grooves form a circularannular tube. (See Figs. 4 and G.) Each tool has its tang 9 extended somewhat beyond the usual length, the extension being flattened out and provided near its extremity with a short projecting pin 10, as shown more particularlyin Fig. 4. The iiattened portion fits into the slot 5 between two of the cheeks, and the pin tits in the circular annular tube of the iiange. This forms a hinge upon which the tool may be swung as desired either for aftixing in the socket of the brace for work or for returning to its place along the sleeve when done with. By undoing the set-screws the disks maybe separated and any tool can be detached either for removal or for replacement by one of the same or another kind. At the other end of the sleeve is another flange 12, having a series of recesses 13, corresponding in number and position to the radial slots 5 in the disks 3 and 4 and of various sizes and shapes to receive the points of the tools 8, as shown more particularly in Fig. 5. In

order to retain the points of the tools in position in these recesses, I provide a cap 14,1-g-

ICQ

idly secured to the spindle 19, having in a convenient part an opening 15, through which the point of the tool may be lifted. A sliding plate 1G is secured to the outside of the cap, whereby this opening may be closed.

In the construction shown in Figs. 1 to 6 the sleeve l is mounted so as to be capable of rotation upon a spindle 19, one end of which is screwed into the handle of the brace and the other end is supported by a stay 20, secured to the tool-socket 18.

In the construction shown in Figs. 7 to 10 the sleeve is mounted upon the stem 21 so as to be freely rotatable thereon, the tool-holding socket being formed in the bottom of the stem 21.

When one of the tools is to be used, the sleeve is turned on the spindle until the point of the tool required is beneath the openingin the cap. The sliding plate is then pushed up and the tool swung around on the hinge at the tang end. The sleeve is rotated on the spindle until the tool is immediately in front of and adjacent to the openingin the side of the socket. It is then turned into place through such opening and secured by turning the thumb-screw.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a tool-holder, the combination with a main or body portion, of a shaft held rigidly thereby, a sleeve mounted to turn on the shaft, means at the outer end of the sleeve for pivotally mounting the tools, a flange attached to the inner end of the sleeve and having notches to receive the ends of the tools to hold the same, a cap loosely mounted on the shaft and having its edge turned toward the tools to embrace the fiange and hold the tools in the notches thereof, the cap having an opening in a portion of its edge, and a slidable cover mounted on the cap and adapted to project over the opening to close the same.

2. In a tool-holder, the combination witha main or body portion, of a shaft mounted rigidly thereon, a sleeve mounted to turn 011 the shaft, a disk integral on the outer end of the sleeve and having notches in its edge, a second disk fastened on one side of the first disk and having notches in its edge registering with the notches in the first disk the disks having annular grooves in their adjacent faces which match with each other to form an annular passage or bearing, tools having their tangs fitted in the notches of the disk and provided with pivots bearingiu the said annular passage or bearing of the disks, and a third fiange carried rigidly at the inner end of the sleeve and having notches to receive the ends of the tools.

3. A tool-holder, comprising a rotatablymounted sleeve, means at one end thereof for pivotally mounting the tools, a fiange in the other end thereof with notches which receive the free ends of the tools, a cap mounted loosely adjacent to the Hange and having its edges turned over to embrace the same, to hold the tools therein, the cap having an opening at one edge, and a slidable cover mounted on the cap and adapted to close said opening. 'i

4. A tool-holder, comprising a revolublymounted member carrying the tools, a cap mounted adjacent to one end of said member to inclose portions of the tools, to hold them in place, the cap having an opening permitting the tools to swing outward, and a slidable cover commanding said opening.

5. In a tool-holder, the combination of aV revolubly-mounted member, a disk attached thereto, a second disk attached to the firstnamed disk, the disks having circular grooves matching to form an annular passage or bearing and the disks also being notched in their edges, and tools fitted in the notches and having their pivots mounted in said bearing.

6. The combination of arevolubly-mounted sleeve, a disk secured rigidly to one end thereof and formed with notches in its edge and with an annular or circular groove, a second disk fastened to the first-named disk and having notches registering with the notches therein, and a groove registering with the groove therein, the said grooves forming a circular passage or bearing, tools, the tangs of Which are fitted in the registering notches of said disks, the tools having the pivots mounted in the said bearing or passage, and a third disk fastened to the opposite end of the sleeve and notched in its edge to receive the free ends of the tools.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

WILLIAM HENRY CHAINE HARRISON.
